Diagram 4: Venusian days and years
It is true that Venus is the only planet with a period of rotation
which
is longer than its period of revolution (year). But it must be
remembered
that the rotation of Venus is retrograde (backward compared to
Earth).
Therefore, if we start at noon local time (Sun is on the reference
meridian
[north south line]), in the time it takes Venus to make one eighth of a
rotation (about 30 Earth days) it will have traveled about one seventh
of a revolution, and it is past sunset. At a little more than
half a revolution and a
little less than half a rotation, it is noon again completing the first
day.
Venus will complete its first year a little before noon ends the second
day.
Sun rises in the west and sets in the east.
